More breaking changes to beta sharing endpoints

We are making breaking changes to the beta sharing endpoints, which will take effect as of February 24th, 2016:

Reorganizing some error structures

Changing the format of shared folder IDs

These changes help make error handling more intuitive and provide a better migration path for apps still using v1 endpoints.

Error Structure Changes

We’re improving and reorganizing the error structures for the beta sharing endpoints. For apps handling errors, changes will not be backwards compatible, but they will make error handling more intuitive in the future, especially as more features are added.

/check_job_status errors

Errors returned by sharing/check_job_status will be grouped by route, to make it clear what type of asynchronous job failed and to allow for route-specific errors. This change will allow different asynchronous routes to raise different errors, without affecting the error types allowed by sharing/check_job_status.

JobError will include the following error tags:

unshare_folder_error for sharing/unshare_folder jobs

remove_folder_member_error for sharing/remove_folder_member jobs

Old

JobError.access_error
JobError.member_error

New

JobError.remove_folder_member_error
JobError.unshare_folder_error

Here’s what sharing/check_job_status will return if sharing/unshare_folder_error fails with the not_a_member error:

Changes to SharedFolderAccessError

We’re taking the error tags no_permission and team_folder out of SharedFolderAccessError, and moving them to error unions associated directly with specific sharing endpoints.

We’re doing this because SharedFolderAccessError should mean that the user cannot access the shared folder. We use no_permission to mean that the user cannot perform a particular operation on a shared folder, but the user may actually be able to access the shared folder. Similarly, team_folder means that a particular operation is not applicable for team folders, not that the user cannot access this folder.

We have added no_permission and team_folder to the error types of applicable routes. For example, AddFolderMemberError and UnshareFolderError now include no_permission and team_folder.

The following routes are affected:

sharing/add_folder_member

sharing/mount_folder

sharing/relinquish_folder_membership

sharing/remove_folder_member

sharing/transfer_folder

sharing/unmount_folder

sharing/unshare_folder

sharing/update_folder_member

sharing/update_folder_policy

The following routes raise SharedFolderAccessError directly, but they are not affected because no_permission and team_folder do not apply.

sharing/get_folder_metadata

sharing/list_folder_members

sharing/list_folder_members/continue

Shared Folder ID Format Change

We are changing the tags shared_folder_id and parent_shared_folder_id in the API response from an encoding string(dbsfid:BCcDKIi3BO5uA9Kzv1v7I9MBJiqoXZXx7Fo) to a raw id string(123456). This is equivalent to the id returned in API v1.

The following routes are affected as they return shared_folder_id or parent_shared_folder_id:

/files/copy

/files/create_folders

/files/delete

/files/download

/files/get_metadata

/files/get_preview

/files/get_thumbnail

/files/list_folders

/files/list_folders/continue

/files/move

/files/restore

/files/search

/files/upload

/files/upload_session/finish

/sharing/check_share_job_status

/sharing/get_folder_metadata

/sharing/list_folders

/sharing/list_folders/continue

/sharing/mount_folder

/sharing/share_folder

/sharing/update_folder_policy

To facilitate migration, the following endpoints will accept both encoded and raw shared folder ID:

/sharing/add_folder_member

/sharing/get_folder_metadata

/sharing/list_folder_members

/sharing/mount_folder

/sharing/relinquish_folder_membership

/sharing/remove_folder_member

/sharing/transfer_folder

/sharing/unmount_folder

/sharing/unshare_folder

/sharing/update_folder_member

/sharing/update_folder_policy

We will monitor usage of encoded shared folder IDs and disable support once usage has stopped.

If your app stores encoded shared folder IDs, you should migrate to the raw IDs by calling /sharing/get_folder_metadata with the encoded IDs to retrieve the raw ID for each stored folder.

New /sharing/list_mountable_folders endpoint

We are introducing a new pair of endpoints, /sharing/list_mountable_folders and /sharing/list_mountable_folders/continue, which return a list of shared folders that more closely matches the shared folders shown on dropbox.com/share. These new endpoints should be preferred over the current /sharing/list_folders[/continue] pair, which will remain in beta.

Please note: Sometimes we blog about upcoming products or features before they're released, but timing and exact functionality of these features may change from what's shared here. The decision to purchase our services should be made based on features that are currently available.
